Caret brings system-wide AI autocomplete to macOS with a single keystroke: Tab. Unlike tools that require you to open a specific app or switch contexts, Caret operates at the OS input layer — any text field, any application, anywhere on your Mac. It reads the surrounding text for context and offers completions inline, with zero UI chrome. The implementation uses macOS Accessibility APIs to hook into the text input stack across all applications. Context is gathered from the active window's text content, and completions are generated via a cloud LLM (with local model support on the roadmap). There's no menu bar app cluttering your workflow — just Tab when you want help, nothing when you don't. The simplicity is the product. While Raycast, Copilot, and similar tools add layers of UI, Caret bets that the right abstraction is "Tab, everywhere." For high-volume writers, support staff, and developers who live in diverse tools all day, this is the kind of ambient AI that actually reduces friction rather than adding it.

CraftBot is a self-hosted, proactive AI assistant that runs locally 24/7. Unlike chat-based AI tools, it continuously works toward user-defined objectives — breaking them into tasks and initiating action rather than waiting to be prompted. Its standout feature is Living UI: custom apps and dashboards the agent builds inside CraftBot that stay aware of their own state, letting the agent read, write, and act on UI data directly. Users can import, build, or evolve Living UIs as their needs change, turning CraftBot into something between a personal agent and a self-modifying software platform. MCP integrations, Skills, and external app connections let it reach into third-party services while remaining fully local. The agent harness is MIT-licensed. CraftBot first launched on Product Hunt on April 18, 2026, earning #3 Product of the Day with 263 upvotes. Today's re-feature on Product Hunt's front page (123 votes) follows a significant update shipping the Living UI evolution system — where UIs built by the agent adapt in real time as your goals and workflows change.
Reviewer scorecard
“Hooking into the macOS Accessibility layer for universal autocomplete is exactly the right architecture — no app-specific plugins, no context-switching. If the latency is under 200ms this is an instant productivity multiplier for anyone who types for a living.”
“The Living UI concept is genuinely novel — having the agent maintain awareness of custom UI state and act on it directly blurs the line between app and agent in a productive way. Self-hosted with MCP support checks all the right boxes for privacy-conscious developers who want real automation.”
“Accessibility API access is a significant permission to grant any app — this tool can see everything you type in every application. Until there's a clear privacy audit and local model option, the security surface is hard to accept for professional use.”
“A 'proactive' AI running 24/7 sounds great until it's doing something you didn't intend at 3am. The Living UI concept is interesting but means you're trusting a locally-running agent to mutate your own tools autonomously. Requires careful configuration and a level of trust most users haven't earned with any AI system yet.”
“System-level AI input layers are the next frontier after app-level AI. Caret is the first credible Mac implementation — expect Apple to build this natively into macOS within 18 months, validating the concept while commoditizing this specific product.”
“Software that evolves its own interface based on how you actually use it is a genuinely new interaction paradigm. CraftBot is an early implementation of something much larger — the self-modifying personal software stack where apps and agents are the same thing.”
“As someone who writes across Notion, Figma, email, and Slack simultaneously, a context-aware Tab that works everywhere is the dream. No mode-switching, no copy-paste to an AI chat window — just inline continuation of your own voice.”
“A proactive creative assistant that builds its own tools around my workflow is exactly what I've wanted. The Living UI concept applied to a content calendar or creative project board could be genuinely transformative for how I manage long-form projects.”
